Research summary

This study reviews data-analysis challenges for Taiji and introduces a more realistic simulation platform for space-based gravitational-wave observations. Taiji Data Challenge II and the Triangle toolkit combine source populations, instrumental effects, orbital dynamics, and time-delay interferometry to support the development and evaluation of global-analysis and end-to-end detection pipelines.

Extended notes

The platform brings overlapping gravitational-wave sources and instrumental effects into a shared simulation environment. The accompanying toolkit supports customized data generation for pipeline development.
